E4438C使用IVI-COM运行ARB波形如何打开ARB输出

大家好,我正在使用matlab通过IVI-com驱动程序控制E4438C VSG。到目前为止,我已经找到了如何加载驱动程序,连接到设备,甚至上传&
选择ARB波形。
但是,就我而言,我无法弄清楚如何打开ARB输出。
当前代码:%create objectvsg_obj = instrument.ivicom.IviRFSigGen('device_name');%initialize objectvsg_obj.Initialize('device_name',true,true,'');%set frequency&
levelvsg_obj.RF.Frequency = 1E9; vsg_obj.RF.Level = 0;%load waveform,i_data&
q_data预先生成 - AWGNvsg_obj.DigitalModulation.Arb.WriteWaveform( 'arb_waveform',I_DATA,q_data,假);%选择最近上传waveformvsg_obj.DigitalModulation.Arb.SelectedWaveform = 'arb_waveform';上RF outputvsg_obj.RF.OutputEnabled%转
= true;但是,此时,写入噪声未被发送出去。
我必须手动按下按钮才能让它工作。
必须有一种方法来打开它,但我找不到哪里。还有,有没有办法通过IVI-com驱动程序发送SCPI命令?

  Hi all,

I'm using Matlab to control a E4438C VSG via the IVI-com drivers.

So far, I've figured out how to load the drivers, connect to the device, and even upload & select an ARB waveform. However, I, for the life of me, cannot figure out how to turn the ARB output on.

Current Code:

%create object
vsg_obj = instrument.ivicom.IviRFSigGen('device_name');
%initialize object
vsg_obj.Initialize('device_name', true, true, '');

%set frequency & level
vsg_obj.RF.Frequency = 1E9;
vsg_obj.RF.Level = 0;

%load waveform, i_data & q_data are generated previously - AWGN
vsg_obj.DigitalModulation.Arb.WriteWaveform('arb_waveform', i_data, q_data, false);
%select the recently uploaded waveform
vsg_obj.DigitalModulation.Arb.SelectedWaveform = 'arb_waveform';

%turn on RF output
vsg_obj.RF.OutputEnabled = true;


However, at this point, the write noise is not being sent out. I have to mannually hit the arb on button to get it to work. There's got to be a way to turn it on, but I can't find where.


Also, is there a way to send SCPI commands through the IVI-com drivers?

嗨 - 在已配置驱动程序的情况下,您可以发送SCPI命令以打开ARB。
这是SCPI命令:[:SOUR]:RAD:ARB ON问候 -

  Hi -

With the Driver already configured, you can sent the SCPI command to turn on the ARB.  Here’s the SCPI command: [:SOUR]:RAD:ARB ON
